RESUMO
Nitric oxide (NO) has been shown to prevent neointimal hyperplasia and decrease atherosclerosis in several animal models. It is a major modulator of vascular homeostasis and has vasoprotective effects against atherosclerosis. However, NO-based therapies with such purposes have not been used in the clinical arena. Our objective was to combine a medical grade elastomer and an NO donor, diethylenetriamine NO adduct (DETA/NO), to determine whether its perivascular administration can attenuate atherosclerosis and vascular injury. Aortic intimal injury was produced using paediatric pulmonary valvoplasty catheter in 22 healthy male New Zealand White rabbits, which were fed a high-cholesterol diet for 4 weeks beforehand. A mixture of the elastomer Silastic and DETA/NO was applied locally to cover the aortas in the experiment group. After 6 additional weeks on the high-cholesterol diet, the aortas and blood samples were harvested for pathologic analysis and comparison with the control group. Mean atherosclerosis and vascular injury surface area was 6.68 x 10(5) microm2 in the experiment group, compared with 3.44 x 10(5) microm2 in the controls. However, there was no statistically significant difference in atherosclerotic surface area between the two groups. Perivascular application of the NO donor DETA/NO, in the concentration we used, did not prevent atherosclerosis in high cholesterol-fed rabbits. This finding prompts more careful assessment before possible clinical uses.

PURPOSE: Caesarean delivery in the absence of any medical indications has become a major issue of concern among the women's health professionals. The patients' choice of caesarean is influenced by several factors predominating by their physicians' suggestion. Our objective was to examine factors that may affect the physicians' responses to patients consulting the mode of delivery. METHODS: Questionnaires were posted to 1,000 female obstetricians and gynaecologists practicing in Tehran in winter 2007. Questionnaires included demographic information of physicians and their history of pregnancy and delivery. Finally, they were asked their preferred mode of delivery and the mode they suggest when being consulted by parturient. RESULTS: From 1,000 physicians, 785 cases (78.5%) responded to the survey. The rate of responses in favour of suggesting normal vaginal delivery, Caesarean Section and painless vaginal delivery was 60.8, 25.6 and 13.6%, respectively. There was a correlation between the suggested and the preferred mode of delivery, it means that the physicians mostly suggested their self-preferred mode of delivery to their patients. CONCLUSIONS: Physicians normally suggest to their patients as the safe mode of delivery what they prefer for themselves. This preference and subsequent suggestion is influenced by different factors including their age, marital status, and previous modes of delivery. As conclusion, it is inferred that informing a physician to choose the right mode of delivery for herself leads to better suggestions to the patients.

BACKGROUND: Endometriosis is the presence of endometrial glands and stroma in sites other than the uterine cavity, which is associated with infertility. The objective of this study was to evaluate the effect of laparoscopic surgical treatment on clinical pregnancy in infertile women with minimal or mild endometriosis. MATERIALS AND METHODS: This clinical trial study was performed in infertile women who were referred to the gynecological clinic between April 2008 and March 2009. After confirmation of minimal or mild endometriosis by diagnostic laparoscopy, patients were randomly assigned into two groups using consecutively numbered, opaque sealed envelops. The first group consisted of women who only underwent diagnostic laparoscopy (no treatment) before randomization. The second group of patients underwent operative laparoscopies. T-test and chi-square test were used when appropriate. A p-value less than 0.05 was considered statistically significant. RESULTS: Analysis with 38 patients in each group showed characteristics such as age, body mass index (BMI), and duration of infertility were statistically similar in both groups. At 9 months follow- up, 9 (24%) women who had operative laparoscopies became pregnant compared with 7 (18%) women in the diagnostic laparoscopy group. The pregnancy rate showed no statistically significant difference between both groups (p=0.49). No complications were reported in either group. CONCLUSION: The present study suggested that laparoscopic surgical treatment was not superior to diagnostic laparoscopy in pregnancy occurrence in infertile women with minimal and mild endometriosis.

RESUMO
BACKGROUND: There exists a high prevalence of psychiatric disorders in dermatological patients. Although, investigators have evaluated psychiatric aspects of the patients suffering from skin diseases; there are rare studies concerning mental health in pemphigus patients. The objective of this study was to evaluate mental health status and quality of life of newly diagnosed pemphigus patients. MATERIALS AND METHODS: Between April 2007 and June 2008, all newly diagnosed pemphigus patients attending the outpatient clinic of a dermatological hospital were given a questionnaire comprising the GHQ-28 and DLQI to fill out. RESULTS: Of 283 patients, 212 complete forms were returned. The bimodal score of GHQ ranged from 0 to 26 (Mean = 9.4) and the Likert score of GHQ ranged from 6 to 68 (Mean = 31.9). The DLQI score ranged between 0 and 30 (Mean of 13.8). A total of 157 patients (73.7%) were yielded to be possible cases of mental disorder considering GHQ-28 bimodal scores. Significant correlation was detected between the DLQI score and bimodal and Likert scoring of GHQ-28. CONCLUSION: Our study has depicted high prevalence of psychiatric comorbidity in pemphigus patients. It underlines the fact that physicians, who are in-charge of care for these patients, are in an exceptional position to distinguish the psychiatric comorbidity and to take appropriate measures.
